    After in-depth understanding, Wang Xueqian discovered that Nikola Tesla's research was very unreliable and had no significance for mass production.  It seems that this old man also knows that the reason that affects turbofan engines is not theory or technology, but materials.  Materials cannot be false at all, and the seriousness of metallurgy is even more cruel than theoretical research.  Because every material that may be used in the engine needs to be tested. If the right material is not found, it means that we have gone astray.  However, even if you find the right materials and still cannot use them, whether it is a turbofan engine or a jet engine, there is one factor that restricts this kind of super engine: temperature.  The turbofan engine is pretty good. The tail flame temperature does not exceed 800 degrees, while the temperature of the jet engine is higher. So what about the combustion chamber?  Whether the machine can work stably in high temperatures and whether it can withstand the test, the plane has to fly into the sky, so we can't be careless.  Solving the problem of materials is not enough, there is another problem, the problem of aircraft cooling.  If these technologies are all used on aircraft, the cost of an aircraft will not increase by one or two times, but by ten or twenty times.  Nikola Tesla is obviously not prepared to take this road of no return, because no company will support his research in practical fields. In the short term, this is a road of no return with no end in sight.  Hope of success.  He was just going to study it in the experiment, start the engine, and tell the world that an airplane does not necessarily need a propeller to get into the sky. The starting time may be ten seconds or one minute, that's all.  The design is then used to obtain a patent for the invention.  Wouldn't it be unfair if Wang Xueqian bumped heads and patted his chest and said he supported Nikola Tesla's research?  Because this is a bottomless pit, a bottomless pit with no end.  ¡°At least at the current level of technology, and it¡¯s still the level of technology in the United States, there is no way in industrial manufacturing that this super engine can be assembled into an aircraft.  The manufacturing industry in the Republic of China was still in its infancy, and it was estimated that even an engine turbofan could not be processed.  This is not a problem of accuracy, but that the machine tool cannot process it.  In order to ensure the durability of components, turbofan engines have to adopt the most stringent processing standards. For example, the blades of engine turbofans need to be formed in one piece, which means that a piece of metal must be processed from several sides at the same time. There is no such machine tool in the United States.  This is why research on jet engines has lasted for more than half a century, and laboratory results have proven feasible.  However, it has repeatedly encountered obstacles in the practical field. The United Kingdom, the United States, and France are not optimistic about this technology. This is still an ordinary department, the military.  After thinking through this, Wang Xueqian immediately stated that he supported Nikola Tesla¡¯s research and that he could purchase the design patent.  If it is a simple design patent, it will not cost much at all!  Nikola Tesla licked his lips. Older people inevitably have this habit. Dry skin is normal, especially the lips, but Wang Xueqian knew that this man was disappointed.  If it was a theoretical design, he could have done it by investing thousands of dollars in a few tens of seconds of laboratory testing.  But what happens after it¡¯s done?  Still, no one has confidence in this kind of engine. Without confidence, there will be no greater investment and the price will not be high, right?  Although Nikola Tesla used to be the kind of person who didn't care, if he hadn't gone through bankruptcy, he might still be the kind of person who went all the way to the dark side, insisted on getting the patent out, and even put it into mass production.  But after living in those days where even eating was controlled by others, the old man seemed to have an inexplicable sense of crisis.  I have to regret to see that Wang Xueqian is no longer interested in his research. Perhaps only when the radar that Wang Xueqian needs is developed and investors trust him, will Wang Xueqian support his research.  A project leader is still a foreigner.  If you want to gain the trust of investors, especially the trust of government investors, you have to make some sacrifices.  Confidentiality Agreement.  Patent confidentiality regulations.  ??Special use of funds ?There are many and varied terms. Nikola Tesla considers himself a veteran. Seeing a lot of legal documents and terms, his head suddenly became big.  Dense beads of sweat oozed out from his forehead, glistening like a guest who had been scalded by hot water in a Turkish bathhouse. He felt exhausted and helpless.  Finally, he gritted his teeth and signed the deal.  Wang Xueqian watched Nikola Tesla sign the document cooperatively, and was a little surprised. Many terms were negotiable, but Nikola Tesla sighed in his heart: "After all, he is an engineering man, and in law  Nothing can change the feeling of powerlessness in front of you. "This is why so many inventors cannot succeed unless they become their own boss.  For example, Edison, Colt, Nobel and others have achieved extraordinary success, but after all, they are very few.  Otherwise the result is likely to be something likeLike Gula Tesla, he once had a rich family, but in the end he found that he could not even hold on to his only wealth.  Nikola Tesla still doesn¡¯t know that the ¡®deed of sale¡¯ he signed means that this old bone will be buried in the Republic of China.  The old man, who felt a little tired, also carefully told Wang Xueqian that the staff in his laboratory must need his approval.  This made Wang Xueqian greatly moved, and he thought a little regretfully: "When the May 1st Labor Medal is issued in two years, give one to the old man." Chen Bulei also breathed a sigh of relief. In his opinion, Wang Xueqian's love for Nicholas?  Silla¡¯s attention is a bit too much.  Fortunately, everything is coming to an end and their trip will return to Shanghai.  He gathered his energy to deal with more complex diplomatic negotiations, but the next day, Wang Xueqian seemed to have forgotten about Shanghai and accompanied Nikola Tesla to the Shipping Bureau.  Because of the impromptu idea, mainly Nikola Tesla said: "The role of ship radar will not only be used for commercial purposes, but also for military purposes." Well, plane radars can be installed on ships.  , it will definitely be used on warships.  But when he went to Mawei Shipyard, Wang Xueqian regretted it. With a face like Nikola Tesla's, he stared at the largest warship in the shipyard with a look of disdain that was beyond words.  This old boy was very popular in the United States back then, and the military also had projects looking for him.  He had naturally visited the military port. Compared with the American battleships, the cruiser Haiqi was as inconspicuous as an inferior barge.  The old guy spat poison in his mouth and said: "I'm sorry, I didn't know that the warships of the Republic of China were of this size. Such warships would not be of much use if they were equipped with radars." The technology of ship plane radar is not very mature to begin with, and is mainly affected by ships  Due to space constraints, a radar that is too large cannot be used, and there are great flaws in power and transmission frequency.  The key is that technology does not support reducing the size of the radar without losing functionality.  Thirty kilometers of early warning is the ultimate, but for a battleship, thirty kilometers is already within the range of the main gun.  Of course, the space of the battleship can be larger, and the scale of the radar can also be larger. Naturally, it will not be as small as thirty kilometers.  Old Mr. Wei Han was so angry that Nikola Tesla, a foreign monk from the United States, was half-dead. Maybe he was deliberately making things difficult. He had a problem.  Of course, this is also a problem for Mawei Shipyard. As a result of the naval battle at the Yangtze Estuary, the torpedo boat force reported very dissatisfied with the stability of the torpedoes.  Two out of six shots seemed to be a passing result.  However, half of them lacked power, causing them to sink, and some of them deviated. Anyway, the naval combat forces were very dissatisfied with the torpedoes manufactured by the shipyard.  Mr. Wei Han and his engineers decided to take the road of independent research and development, and that was the end of imitating American gas torpedoes.  If existing technology can be used to transform better torpedoes, the improvement in stability and power will allow the torpedoes to adapt to more complex battlefields.  Among the several research and development projects selected by the project team, torpedoes powered by diesel engines have become a concern.  It can provide stable power, the speed is relatively average, and the speed can also be improved.  But there is a problem. Diesel engines need air to operate, which cannot avoid producing a large number of blisters like gas torpedoes.  When the distance is far, it is easy for warships to evade.  As the distance gets closer, the pressure on the torpedo boat will increase.  Nikola Tesla didn¡¯t mean to show cowardice at all. As an inventor, he was fundamentally different from a scientist.  Whether it¡¯s weapons or civilian machinery, he¡¯s always cool with it.  He was not as pretentious as a scientist, but visited the shipyard with great interest.  Provide some suggestions for improvement.  Although Wei Han was amazed by these little suggestions, the two old men seemed to be competing against each other.  On the contrary, Wang Xueqian enjoyed it. Wei Han was actually out of touch with the times. He was a shipbuilder, but he was stuck at the level of the 1990s, which was more than thirty years ago.  There are many reasons. The main reason is that after the Sino-French War, the Qing government's navy had ceased to exist in name only, and it was impossible to continue to invest in the Mawei naval port. In fact, Mawei's decline occurred after the Sino-French War, earlier than the Sino-Japanese War.  Mr. Wei himself knew that he had not designed or built a warship in thirty years, and his knowledge had fallen far behind the modern navy.  He has left the armored cruiser era, the pre-Dreadnought era, the Dreadnought era, and the recent new Dreadnought era, which is the super battleship era.  Perhaps as a shipbuilder, he has fallen behind.  But as a naval man, Mr. Wei does not feel that he is out of tune with the times.  He knew what Wang Xueqian meant from the moment Wang Xueqian put the two largest warships into the naval port dock for renovation.  The Southeast King does not seem to be preparing to develop a big naval era.  Wei Han, who led a team to visit Europe and the United States in the early 1920s, understood that relying on the national strength of the Republic of China to catch up with the era of great naval development hadIt's no longer possible.  The huge investment was simply beyond what the Republic of China could afford.  Even for a country like Japan that has entered the industrial age, its navy has never fallen behind due to its weak foundation.  However, due to limitations in national strength, developing the number of navy and building first-class warships and naval personnel has almost exhausted the country's finances.  What's more, the Republic of China was even worse financially than Japan?  How can Wang Xueqian develop a large navy with only the finances of one place?  The only way is to change naval attack weapons from battleship-heavy one-ton shells to more vicious torpedoes.  In Mawei, he is also the most supportive of Wang Xueqian¡¯s strategic deployment.  Since the country cannot invest all its resources in the navy, the navy must bear this concession.  But giving in does not mean that we no longer want the navy.  Warships cannot be built too large, but they can have submarines and torpedo boats to use offshore defense to guard coastal defenses.  It has to be said that the naval battle at the Yangtze Estuary gave Wei Han a lot of confidence. A 10,000-ton British cruiser was damaged and the entire fleet was destroyed, which showed that Wang Xueqian was on the right path.  The only thing missing is the means of attack, which is too simple.  Torpedo boats cannot be the only attack means of torpedoes. With the enrichment of torpedo aircraft and submarines, the self-protection capabilities of the Republic of China Navy will be further strengthened.  Germany's submarine warfare after the Battle of Tehran in World War I allowed him to see another direction for the navy.  It can still frighten opponents, but it will require fewer resources.  A battleship requires about two thousand officers and men, or even more.  But for a submarine force, two thousand officers and soldiers is the number of officers and soldiers of a submarine force, and a submarine only has a few dozen people.  The threat it brings can sink a battleship in an instant.  With such defensive means, it was possible for the Republic of China to break away from the carvings of the great powers.  ¡°In the future, torpedoes will be a key weapon for the Republic of China Navy.  Mr. Wei Han took Nikola Tesla to the two-story building where he was responsible for the design. Several engineers were arguing over their own designs.  "Abandon the propeller as thrust and directly use the combustion chamber for propulsion." "In this case, because the thrust is too large, the torpedo will tilt up and directly go out of the sea due to the too large thrust of the tail at the beginning of startup. The thrust is too small.  "If the speed is too full, the hit rate will be greatly reduced." "It is better to use a diesel engine. Only a small amount of diesel can ensure the stable power of the torpedo." "Don't forget that a large amount of unburnable air will form bubbles.  , the warship will follow the trajectory of the bubbles and dodge. This solution is not suitable for torpedoes at all. It is better to use American gas torpedoes. Anyway, we can imitate them. " "It is better to use electricity, without any gas generation, to launch the torpedoes.  In an instant, the people on the warship would only find out when the torpedo was very close to the warship, at least within a few hundred meters. By then, there would be no chance to avoid the torpedo. " "But the area occupied by the battery is too large.  , so the torpedo will be forced to be very large. It can only be launched by ship, and the larger the weight and size of the torpedo, the faster it will be in the water.  Torpedoes cause more difficulties. "" Nikola Tesla has been silent since Wei Han brought him in.  When the engineers at Fuzhou Shipyard seemed to be arguing, he glanced at Wei Han and coughed lightly: "Gentlemen!" Who is this old man?  ¡°I don¡¯t know that this is a confidential area of ??the shipyard. Anyonewell, since Mr. Wei Han brought the person in, there must be no problem.  And there is no need to worry that the engineers from the Shipping Bureau cannot understand English.  Fuzhou Shipping Bureau School English is a compulsory course, and the teaching method is based on the standard of studying in the United Kingdom and the United States.  So no one will be surprised by Nikola Tesla's sudden appearance in English.  "Why not continue to study diesel engine-powered torpedoes?" Nikola Tesla gestured: "The torpedo is not big, but the diesel engine is very powerful, and it can be placed on the torpedo as long as there is not much space."  "But after the air is discharged, how to solve the bubbles?" Nikolai Tesla blinked his bright eyes and smiled: "Why not use pure oxygen? You must know that as long as pure oil is burned, there can only be another substance.  , water and carbon dioxide. The bubbles are caused by the nitrogen in the compressed air, and carbon dioxide can quickly dissolve in water. " Mr. Wei's hand holding his beard suddenly froze, and he didn't think it was bothering him.  The long-standing technical problem between the shipyard engineer and himself was solved by Nikola Tesla less than ten minutes after Nikola Tesla entered the room.  But for people who are not originallyFor the old Wei Han, the feeling of being crushed in terms of IQ is very uncomfortable and frustrating.  He decided to embarrass Nikola Tesla a little and said: "Pure oxygen will be fully burned, and it will greatly increase the temperature of the cylinder inside the engine, which will cause damage to the engine in a very short time." In this regard.  To make things difficult, Nikola Tesla smiled without showing any timidity: "You are talking about torpedoes, right? As far as I know, the working time of torpedoes generally does not exceed five minutes. Does it mean that the torpedoes you are going to make need to work?"  An hour? "This is not difficult at all for Nikola Tesla.  He was a physicist, an electrical engineer, and an inventor.  But don't forget, he is an inventor, and inventors are a group of paranoid people who exist to solve difficult problems.  They may not be top theorists and cannot teach advanced academics in universities, but they are all highly capable solution solvers, and they all exist across industries.  This is the difference between inventors and engineers. The former may not be as professional as the latter, but the latter will definitely look up to inventors when it comes to solving problems.  Because for engineers, difficulties are part of the job, solving difficulties is part of their job, and it is one of the abilities to be hired.  But inventors they regard the difficulties blocking the road ahead as God's test for them, as part of their destiny, and as a fate that must be overcome.  And Nikola Tesla is one of the top few inventors, and his reactions are beyond the reach of ordinary engineers. ?????????????????????? Well, Wei Han has lived so long and has not blushed for a long time because of being looked down upon. But at this moment, he blushed This seems to be common sense.  (~^~)
